Is REST safe to implement using Javascript libraries Backbone, Zepto, and jQuery?

Question

I'd like to use as close to full RESTful style as a browser can manage.

Do Backbone, jQuery, and Zepto to implement the non-browser supported methods PUT and DELETE in the same way? If so, how do they implement this?

Backbone:

myBackbone.model.destroy() // Calls Backbone.sync('DELETE', model, options)

jQuery / Zepto:

$.ajax({ url:'/testUrl', type:'PUT' })

What makes you think browsers don't support PUT and DELETE? They are supported in all major browsers. See http://stackoverflow.com/questions/165779/are-the-put-delete-head-etc-methods-available-in-most-web-browsers — Benjamin Gruenbaum, Mar 07 '13 at 23:05

Support for all HTTP methods in *HTML Forms* is not supported in older browsers. That does not apply to JS code. More accurately, AJAX is built on top of: http://en.wikipedia.org/wiki/XMLHttpRequest. So if you want to read limitations (or lack thereof) go there. — Matt Whipple, Mar 07 '13 at 23:08
@SimpleAsCouldBe Did you try to run any code that failed before asking? IIRC, old browsers support PUT and DELETE via AJAX — Benjamin Gruenbaum, Mar 07 '13 at 23:09

Apparently REST is safe to trigger from JS, and has been for ages, just not from HTML forms.

@Matt Whipple:

@Benjamin Gruenbaum:

PUT and DELETE... are supported in all major browsers.
